Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The core of the present invention is to provide a walking control system for a scissor-type aerial work platform, which can avoid the phenomenon that the scissor-type aerial work platform slips when driving and braking on a ramp.

[0033] Please refer to figure 1 , is the control principle diagram of the scissor-type aerial work platform walking control system provided by the specific embodiment of the present invention.

[0034] The present invention ...

Abstract

The invention discloses a scissor type aerial work platform walking control system. The system comprises a first hydraulic motor; a second hydraulic motor; a first oil passage; a second oil passage; a third oil path; a fourth oil path; an oil inlet path; an oil return path; an oil inlet P1 of the first reversing valve is connected with the oil inlet path, and an oil return opening T1 of the first reversing valve is connected with the oil return path; a working oil port A2 of the second reversing valve is connected with the third oil way, and a working oil port B2 of the second reversing valve is connected with the second oil way; the fifth oil way is provided with a first balance valve and is respectively connected with the working oil port A1, the first oil way and the oil inlet P2; and the sixth oil way provided with a second balance valve is respectively connected with the working oil port B1, the fourth oil way and the oil return port T2. Through the first balance valve and the second balance valve, the back pressure of oil return oil ways of the first hydraulic motor and the second hydraulic motor is increased, and the oil return resistance of the first hydraulic motor and the second hydraulic motor is large. When the aerial work platform brakes when running on a ramp, the aerial work platform can be prevented from sliding on the ramp.

Description

technical field [0001] The invention relates to the technical field of walking control of an aerial work platform, and more specifically, relates to a walking control system of a scissor type aerial work platform. Background technique [0002] In the construction process of domestic infrastructure construction, rail transit, highways, airports, ports, and large venues, it usually involves the construction of prefabricated buildings and the installation of a large number of steel structural parts. Therefore, the demand for aerial work platforms Large quantity, the scissor type aerial work platform has a large inventory because of its low cost and low rental fee, and can meet the needs of most working conditions. [0003] However, when the scissor-type aerial work platform in the prior art brakes on the slope, it is easy to appear the phenomenon that the slope cannot be braked. [0004] Therefore, how to avoid the phenomenon that the scissor-type aerial work platform slides w...
